Am I being really thick, or does the Merc Prop browser not give diameters?

I realised after Easdlae that my original thought of "up an inch of pitch" is actuially fundamentally flawed, after spending rather more time than was convenient throttling back to let the water back to the prop.......

So, onto the website I went to see what the various options were. Nowhere can I see diameter listed, even in the "specs" tab! (no glasses jokes please! )

Anyone got a decent summary sheet? and could tell me what diameters are available in the various 13 spline (50/60HP bracket) prop ranges.
